Middletown police and Bucks County Detectives were investigating a stabbing in the Langhorne section of Middletown Tuesday evening.

Chief of Police Joseph Bartorilla said a 26-year-old man was in custody for stabbing his 66-year-old father after an argument in a home in the 500 block of Trappe Lane in the Maple Point development. As of 6:30 p.m., the father was in serious condition at St. Mary Medical Center, police said.

Officers took the 26-year-old into custody around 5 p.m. and secured the house so medics could begin working on the 66 year old, according to authorities.

Neighbors said the mother inside the house is ill and needs medical care. Medics from the Penndel-Middletown Emergency Squad arrived around 6:20 p.m. to transport the woman to the hospital due to her condition. Police said she was not injured in the stabbing.

An investigator said the mother was not yet aware of what had happened in the house and that detectives were awaiting medics before telling her.

Bartorilla said the crime scene appeared to be contained to the two-story home.

A county crime scene truck was called to process the scene.

Neighbors and friends of the family milled about the scene while an officer put yellow crime scene tape up around the modest home.

“This usually is a real quiet neighborhood,” Bartorilla said.
